SEDENTARY
Exerting up to 10 pounds of force occasionally and/or negligible amount of force frequently to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and all other sedentary criteria are met.
LIGHT
Exerting up to 20 pounds of force occasionally, and/or up to 10 pounds of force frequently, and/or a negligible amount of force constantly to move objects. Even though the weight lifted may be only a negligible amount, a job should be treated as Light Work if:
- It requires walking or standing to a significant degree;
- It requires sitting most of the time, but entails pushing and/or pulling of arm or leg controls; and/or
- When the job requires working at a production rate pace entailing the constant pushing and/or pulling of materials even though the weight of those materials is negligible.
MEDIUM
Exerting 20 to 50 pounds of force occasionally, and/or 10 to 25 pounds of force frequently, and/or greater than negligible up to 10 pounds of force constantly to move objects. (Exerting force means lifting.)
HEAVY
Exerting 50 to 100 pounds of force occasionally, and/or 25 to 50 pounds of force frequently, and/or 10 to 20 pounds of force constantly to move objects.
VERY HEAVY
Exerting in excess of 100 pounds of force occasionally, and/or in excess of 50 pounds of force frequently, and/or in excess of 20 pounds of force constantly to move objects.

“Frequently” means activity or condition exists from 1/3 to 2/3 of the time in an 8 hour day. (5.33 hours in an 8 hour day)
